From 8f9e0e9f339aee4ce31a338d5f27356eb5457f85 Mon Sep 17 00:00:00 2001 From: Kim Phillips Date: Wed, 15 Aug 2007 22:30:19 -0500 Subject: mpc83xx: remaining 8360 libfdt fixes PCI clocks and QE frequencies weren't being updated, and the core clock was being updated incorrectly. This patch also adds a /memory node if it doesn't already exist prior to update. plus some cosmetic trimming to single line comments.
